It seems to be that way. I can't give you a specific cause and effect, but clearly Europe looks after Europe, I think. It makes its own isotopes, and Europe looks after Europe. We see that at the European meetings.
In North America what happens is you have different supply chain dynamics. In the United States there are probably contractual obligations. There are integrated supply chain streams that give preferential supply into the United States medical communities. There are centralized radiopharmacies in the United States and there are not in Canada. So there are a bunch of supply chain issues.
